在srcmainjava下建立一個Servlet
修改webxml
建立JSP
測試

在上一篇部落格裡，我們使用Maven構建了一個Web項目，我們在這裡寫一個簡單的Servlet，測試一下。

1.在src/main/java下，建立一個Servlet [java] view plaincopyprint?

<span style="font-weight: normal;">package com.deppon.text01.action;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class UserServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request , response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=utf-8");
String action = request.getParameter("action");
if("login_input".equals(action)) {
request.getRequestDispatcher("login.jsp").forward(request , response);
} else if("login".equals(action)) {
String name = request.getParameter("name");
String password = request.getParameter("password");
System.out.println("name->" + name + ",password->" + password);
}
}
}</span>

2. 修改web.xml [java] view plaincopyprint?

<pre name="code" class="html"><span style="font-weight: normal;"><?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<servlet>
<servlet-name>UserServlet</servlet-name>
<servlet-class>com.deppon.text01.action.UserServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>UserServlet</servlet-name>
<url-pattern>/user</url-pattern>
</servlet-mapping>
</web-app></span>

3. 建立JSP

index.jsp

[java] view plaincopyprint?

<span style="font-weight: normal;"><%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Hello Maven</title>
</head>
<body>
<p>大家好！</p>
<a href="user?action=login_input">去登入</a>
</body>
</html></span>

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登入介面</title>
</head>
<body>
<form action="user?action=login" method="post">
Name:<input type="text" name="name" />
Password:<input type="password" name="password" />
<input type="submit" value="登入" />
</form>
</body>
</html>

4. 測試

項目結構如所示：

其實，構建完成之後，開發的話，應該和平時開發Web項目是一樣的。

之前忘記說明pom檔案了，需要添加依賴的：

pom.xml

[html] view plaincopyprint?
